"C'est la vie, mon ami"

These crystal lenses fit over the eyes. They have 12 charges. While wearing them, you can use an action and expend 1 or more charges to cast one of the following spells on yourself: detect magic (2 charges), identify (2 charges), find traps (4 charges), greater restoration (7 charges), true seeing (9 charges). The lenses regain 1d10+2 charges daily at dawn.

If you expend the last charge, roll a d20. On a 1, the crystal lenses shatter and you are considered blinded for the next 1d4 days, which can't be reduced in any way. After this time has elapsed the lenses magically reform and are able to used as normal.
